Effective Prüfer Angles and Relative Oscillation Criteria
We present a streamlined approach to relative oscillation criteria based on effective Prüfer angles adapted to the use at the edges of the essential spectrum. Based on this we provided a new scale of oscillation criteria for general Sturm–Liouville operators which answer the question whether a perturbation inserts a finite or an infinite number of eigenvalues into an essential spectral gap. As ...
متن کاملOscillation Criteria for Delay Equations
This paper is concerned with the oscillatory behavior of first-order delay differential equations of the form x′(t) + p(t)x(τ(t)) = 0, t ≥ t0, (1) where p, τ ∈ C([t0,∞),R),R = [0,∞), τ(t) is non-decreasing, τ(t) < t for t ≥ t0 and limt→∞ τ(t) =∞. Let the numbers k and L be defined by
متن کاملPerturbative Oscillation Criteria and Hardy-type Inequalities
We prove a natural generalization of Kneser's oscillation criterion and Hardy's inequality for Sturm{Liouville diierential expressions. In particular, assuming ? d dx p 0 (x) d dx + q 0 (x), x 2 (a; b), ?1 a < b 1 to be nonoscillatory near a (or b), we determine conditions on q(x) such that ? d dx p 0 (x) d dx + q 0 (x) + q(x) is nonoscillatory, respectively, oscillatory near a (or b).
متن کاملRelative Egalitarianism and Related Criteria
We reconsider the problem of aggregating individual preference orderings into a single social ordering when alternatives are lotteries and individual preferences are of the von Neumann-Morgenstern type. Relative egalitarianism ranks alternatives by applying the leximin ordering to the distributions of (0-1) normalized utilities they generate. We propose an axiomatic characterization of this agg...
متن کاملCurves and coherent Prüfer rings
Usual definitions of Dedekind domain are not well suited for an algorithmic treatment. Indeed, the notion of Noetherian rings is subtle from a constructive point of view, and to be able to get prime ideals involve strong hypotheses. For instance, if k is a field, even given explicitely, there is in general no method to factorize polynomials in k[X]. The work [2] analyses the notion of Dedekind ...
